Solfege and Intervals

Do Re Mi Fa Sol La Ti Do 1 1 ½ 1 1 1 ½

To understand intervals better, you must know the distance between individual solfege syllables in the major scale. 1 means there is a whole step, and ½ means there is a half step between the pitches

Seconds

• Seconds are the interval between two consecutive notes.

• There are two types of seconds- Major Seconds (M2)

One whole step.- Minor Seconds (m2)

One half step.

Quit

Seconds Continued

• Major Seconds in the Major scale

- Do – Re, Re – Mi, Fa – Sol, Sol- La, La - Ti

• Minor Seconds in the Major Scale- Mi – Fa, Ti – Do

Quit

Thirds• Thirds are the Interval between three consecutive

notes• There are two types of thirds

- Major Thirds (M3)Two whole stepsM2 + M2 = M3 (Do – Re) + (Re – Mi) = (Do – Mi)

- Minor Thirds (m3)One whole step and One half stepM2 + m2 = m3(Re – Mi) + (Mi – Fa) = (Re – Fa)

Quit

Thirds Continued• Major Thirds in the Major Scale

– Do – Mi, Fa – La, Sol – Ti

• Minor Thirds in the Major Scale

– Re – Fa, Mi – Sol, La – Do, Ti – Re

Fourths• Fourths are the interval between four consecutive

notes• There are two types of thirds

- Perfect Fourths (P4)Two whole steps and a half stepM3 + m2 = P4(Do – Mi) + (Mi – Fa) = (Do – Fa)

- Augmented Fourths (A4)Three whole stepsM3 + M2 = A4(Fa – La) + (La – Ti) = (Fa – Ti)

Quit

Fourths Continued

• Pefect Fourths in the Major Scale– Do – Fa, Re – Sol, Mi – La, Sol – Do, La – Re,

Ti – Mi

• Augmented Fourths in the Major Scale

– Fa – Ti

Quit

Fifths• Fifths are the interval between five consecutive

notes• There are two types of fifths– Perfect Fifths (P5)

Three whole steps and a half stepM3 + m3 = P5(Do – Mi) + (Mi – Sol) = (Do – Sol)

– Diminished Fifths (d5)Three whole steps

m3 + m3 = d5(Ti – Re) + (Re – Fa) = (Ti – Fa)

Quit

Fifths Continued

• Perfect Fifths in the Major Scale

– Do – Sol, Re – La, Mi – Ti, Fa – Do, Sol – Re, La – Mi,

• Diminished Fifths in the Major Scale

– Ti – Fa
